To stock a lake, a supply of fish (with water) is dropped from an airplane at an altitude of 70 meters. The height of the fish, as a function of time, is h(t) = 120 − 50√ 1.1t + 1 where height, h, is in meters (m) and time, t, is in seconds (s). Answer the following questions. All answers must have correct units.


(a) What is the height of the fish supply at the instant when its velocity is -13 m/s? Be accurate to the nearest meter

____________


b) When the fish supply is 5 meters above the lake, how fast is it moving?

Hi Roz A., You had better recheck the function. Fish don't fall with (t)^0.5 dependence. Ever!! Or at least, confirm if that is 120 - 50*(1.1*t)^0.5 + 1 (looks really weird, why not just 121-50*(1.1*t)^0.5 ?) or rather 120 - 50*(1.1*t - 1)^0.5 or may be even 120 - 50*(1.1(t-1))^0.5 ? All of these have differentiable forms, and they're all equally fishy!! -- Cheers, --Mr. d.
